Review comment:
I guess what @rabbah was after, is that this could now be changed to:
```
// entirely omit the <variable> line
<root level="whisk.loglevel">
```
While defining:
```
-e CONFIG_whisk_loglevel=...
```
on the components.
Your call on what you prefer.
In any case: Is the double-definition even necessary in your case? Couldn't
it be just:
```
<root level="${WHISK_LOG_LEVEL:-INFO}">
```
? If that's possible I'd prefer that, since it avoids the indirection
through the environment transformation script.
